Model-based grades, not lab tests. We flunk more than we pass. How grading works
PFAS in Pizza Stones & Baking Surfaces, Which Brands Grade Best and Worst
Based on available materials and data, the IKEA Nordic Ware Pizza Stone Set currently comes out on top among pizza stones and baking surfaces we've reviewed, with a model-based estimate of 90 out of 100 for lower PFAS-related concern. That score reflects publicly disclosed materials and construction rather than an independent lab test, and it means lower estimated concern, not a guarantee that the product is free of PFAS. At the other end of the spectrum, several Farberware and Sur La Table stones landed in "Bad" territory, largely tied to nonstick coatings and finishing processes that raise more red flags in our scoring model.
This guide compares the pizza stones and baking surfaces we've graded, explains what materials and brand claims drive those grades, and points you toward the categories worth shopping first. As always, these are model-based estimates built from publicly available materials and disclosure data, not laboratory certainty, and no product below is being called "safe" or "PFAS-free."

How we're grading these products
Every grade referenced in this guide is a model-based estimate built from publicly disclosed materials, manufacturer specifications, and known coating or finishing practices for the category. These are not laboratory test results unless explicitly noted, and no grade here should be read as a certification. A high score reflects lower estimated concern based on available information; it does not mean a product is confirmed "PFAS-free" or "safe" in a legal or clinical sense.
The top performers, in detail
IKEA Nordic Ware Pizza Stone Set
Materials, Uncoated ceramic/ceramic-composite stone construction typical of Nordic Ware's baking line. Brand claims, IKEA and Nordic Ware market this as a straightforward baking stone without emphasis on nonstick chemistry; we have not identified a third-party lab verification of PFAS absence. Pros, Highest score in our dataset (90/100), simple uncoated design, widely available. Cons, Still model-estimated rather than lab-confirmed, and porous stone surfaces can absorb oils and require careful seasoning and cleaning over time. See the full listing at IKEA Nordic Ware Pizza Stone Set.
KitchenAid Wall Oven Baking Stones (W10696057 and W10862028)
Materials, OEM ceramic baking stones designed as direct replacements for KitchenAid wall ovens. Brand claims, Sold as genuine OEM parts through Sears PartsDirect, with no explicit PFAS-free marketing language identified in reviewed listings. Pros, Both score 75/100, purpose-built fit for specific oven models, uncoated stone surface typical of this product class. Cons, Limited to specific oven models, and as with all entries here, the grade is an estimate rather than a certified test result. Details, W10696057 and W10862028.
Etsy Hand Painted Daisy Pizza Stone
Materials, Handmade ceramic with painted decorative glaze. Brand claims, Individual artisan sellers typically describe the piece as dishwasher-safe and food-safe glaze, but these are seller statements, not independent lab verification. Pros, Strong 75/100 score, decorative and functional dual-use design. Cons, Glaze composition can vary batch to batch between independent sellers, so consistency is harder to verify than with mass-manufactured brands. Listing, Etsy Hand Painted Daisy Pizza Stone.
The middle tier, "Good" but not top-graded
A large cluster of well-known cookware names, including Sur La Table's Le Creuset Round Pizza Stone Staub's Refractory Pizza Stone, and multiple Wayfair-listed cordierite and ceramic stones, land at 65/100 in our model. These products are typically uncoated cordierite or ceramic stones from established cookware brands, but public disclosure about raw material sourcing and glaze formulation is often incomplete, which caps their score below the top tier. Pros across this group include reputable manufacturing and durable stone construction. Cons include less transparency around glaze and finishing chemistry compared to the top-graded uncoated stones. If you're comparing options in this range, cross-check listings via our Pizza Stones & Baking Surfaces finder before buying.
What to avoid
Four products in our database currently sit in "Bad" territory at 15/100, the Farberware BBQ Round Pizza Stone Farberware Pizza Crisper 13" Wayfair Easylife Tech Non-Stick Ceramic Pizza Stone, and the Sur La Table Cordierite No-Slip Pizza Stone. What links most of these is nonstick or "no-slip" surface treatment, language that often signals a coating layer where fluoropolymer chemistry has historically been common in bakeware and cookware. Based on available materials and data, these products carry higher estimated concern in our model, and shoppers prioritizing lower PFAS exposure may want to consider alternatives from the "Excellent" tier above. As a general rule when shopping outside this list, be cautious of any pizza stone or baking surface marketed as "non-stick," "easy-release," or "no-slip" without a clear, verifiable ingredient or coating disclosure. Compare against broader cookware and bakeware guidance if you're also shopping pans and sheet trays.
